I can confirm same “unknown label” issue is in 19.3 as well. As you say it only appears to be an issue when using the “widgets” on the main screen of Estuary. When adding the movies from within the Movies subcategory on Kodi server there is no issue.

Thanks for checking this. Seem I used another instance of the Remote App when testing this on my side under 19.3. I will create an issue report for Kodi in the next days. Maybe this can be fixed for Kodi 20.
Edit: JSON issue PlayList.GetItems

As for the playlist not being updated, it’s really perplexing me. Now it works fine on my Xbox but it doesn’t update while using Windows. I’ve confirmed tcp is working. I simply can’t explain it.

I will try to test this with my son's setup. Could be missing notifications coming from Kodi.

Let’s say you queue up some content. The playlist has let’s say 3 items.
Now if you use the remote and play something that is not on the playlist it will discard the queued items. Would it not be better to insert this to the top of the current playlist?

There was an issue raised on the same use case, but with a different ask: Instead of deleting the old queue without any notice just raise a popup, if you are ok to delete the current queue or not (issue #84). In fact, the current behaviour exactly matches Kodi's. I think the remote should not deviate from what Kodi does. Or at least as default it should behave same.

Is there a way for the app to detect when passthough is enabled and disable the volume control on the app since it doesn’t actually do anything?

I am not convinced the remote should handle it, imho it will be better to block this in Kodi itself. Obviously it is already handled for other remotes, it should be also blocked for JSON API volume changes.
